Description

Technical Field

[0001] This utility model relates to the field of graphite braided thread processing technology, and in particular to a graphite braided thread winding machine. Background Technology

[0002] Graphite rope, also known as flexible graphite packing, is made of flexible graphite thread through a core-braiding process. Currently, most sealing packings on the domestic market that use graphite as the main raw material are made of pure expanded graphite thread with materials such as cotton yarn, glass fiber, copper wire, and stainless steel wire as internal reinforcing fibers. These packings have high loss on ignition and poor volume stability at high temperatures, leading to poor sealing performance and making them unsuitable for sealing equipment with high sealing requirements. To improve the sealing performance of sealing packings, low-loss-on-ignition graphite packings have emerged on the market. These are typically made of flexible graphite as the raw material, reinforced with imported high-quality high-modulus carbon fiber, and with added pressure-sensitive adhesive. They are then twisted into thread using a composite process and finally braided using a core-braiding process. In other words, graphite braided thread uses flexible graphite thread as the base material and utilizes high-speed metal wire braiding equipment to uniformly wrap a layer of metal mesh around the outer surface of the graphite thread. For example, Inco nickel wire with an outer hook-braided mesh has a uniform texture, causes less friction on bearings than traditional outer braided metal mesh, and has extremely high tensile strength, thus it is widely used in graphite braided thread processing.

[0003] After the graphite braided yarn is produced, it needs to be wound up. After winding, it's crucial to ensure the winding drum is placed stably to prevent the graphite braided yarn from loosening and to facilitate storage. During the winding process, the yarn arrangement can become messy, resulting in an unattractive finished product. Furthermore, the messy arrangement reduces the space utilization of the drum, decreasing the amount of finished product that can be wound. In textile machinery used for producing garment yarn, a yarn guide with a reciprocating screw is typically used to solve this problem. However, graphite rope braiding machines produce thicker yarns, and the metal mesh on its surface creates significant external friction, making it prone to getting stuck in the reciprocating screw. Therefore, a better winding device specifically designed for graphite braided yarn is needed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a graphite braided thread winding machine, which solves the problem that the graphite braided thread is messy during the winding process, resulting in an unattractive finished product, and the messy thread will cause insufficient space utilization of the roll.

[0005] According to an embodiment of the present invention, a graphite braided yarn winding machine includes a base and a support mounted on the base. A winding roller, an adjusting roller, and a tensioning roller are arranged sequentially from bottom to top on the support. The rotating shafts of the winding roller, the adjusting roller, and the tensioning roller are all horizontal and arranged in parallel.

[0006] The take-up roller is connected to a first motor fixedly mounted on a bracket on one side. The adjusting roller includes two vertically arranged connecting plates and two adjusting shafts horizontally installed between the connecting plates. The surface of the adjusting shaft is provided with smooth threads, and the threads on the two adjusting shafts rotate in opposite directions. The middle part of the outer side of the connecting plate is provided with a connecting shaft parallel to the take-up roller. A second motor fixedly mounted on the bracket is connected to one of the connecting shafts.

[0007] Furthermore, the bracket includes two vertically arranged support plates, and the winding roller, adjusting roller and tensioning roller are all rotatably mounted between the support plates.

[0008] Furthermore, the take-up roller includes a take-up shaft and baffles disposed at both ends of the take-up shaft. The baffles are coaxially disposed with the take-up shaft and perpendicular to the take-up shaft. The take-up shaft passes through the baffles and is rotatably connected to the bracket. One end of the take-up shaft passes through the bracket and is connected to the output shaft of the first motor disposed on the outside of the bracket.

[0009] Furthermore, an annular rotating plate is provided on the inner side of the baffle. The rotating plate is arranged around the outside of the take-up shaft, and the rotating plate and the baffle are connected by several annular bearings, so that the rotating plate can rotate relative to the baffle around the take-up shaft.

[0010] Furthermore, the opposite side of the baffle is a flexible rough surface.

[0011] Furthermore, a controller is provided at the power supply of the second motor, and the controller controls the second motor to rotate intermittently in both directions.

[0012] Furthermore, the tensioning roller includes a sliding shaft and a sliding sleeve sleeved on its outside. The sliding sleeve is a roller structure. The sliding sleeve and the sliding shaft are slidably and rotatably connected, so that the sliding sleeve can move freely along the axial direction of the sliding shaft while also rotating around the sliding shaft.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, adjusting rollers are arranged side-by-side above the take-up roller. Each adjusting roller includes two vertically arranged connecting plates and two horizontally installed adjusting shafts between the connecting plates. The adjusting shafts have smooth threads on their surfaces, and the threads on the two adjusting shafts rotate in opposite directions. The rotation of a second motor controls the two adjusting shafts to contact the graphite braided wire. When the graphite braided wire passes over the surface of the adjusting shaft and winds onto the take-up shaft, it drives the adjusting shaft to rotate. This rotation, in turn, drives the graphite braided wire to move towards one end through its threads. This allows the graphite braided wire to move axially while being wound, resulting in a uniform and neat arrangement on the take-up shaft. When the graphite braided wire moves to the end of the take-up shaft from one direction, the second motor rotates accordingly, causing the other adjusting shaft with the opposite thread to contact the graphite braided wire. The graphite braided wire then moves in the opposite direction, winding another layer evenly. This process is repeated to achieve a neat and orderly winding operation. Attached Figure Description

[0019] Figure 2 The dotted line in the middle is graphite braided thread. Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 As shown in the figure, this utility model embodiment proposes a graphite braided yarn winding machine, including a base 1 and a bracket mounted on the base 1. From bottom to top, the bracket is arranged with a winding roller, an adjusting roller 4, and a tension roller. The rotating shafts of the winding roller, adjusting roller 4, and tension roller are all horizontal and parallel. In this embodiment, the base 1 is a horizontal plate structure, and the bracket includes two vertically parallel support plates 2 mounted on the base 1. The winding roller, adjusting roller 4, and tension roller are all rotatably mounted between the support plates 2.

[0022] like Figure 2 As shown, a first motor 7, fixedly mounted on a bracket, is connected to one side of the take-up roller. The take-up roller includes a take-up shaft 3 and baffles 31 disposed at both ends of the take-up shaft 3. The baffles 31 are coaxially disposed with the take-up shaft 3 and perpendicular to the take-up shaft 3. The take-up shaft 3 passes through the baffles 31 and is rotatably connected to the bracket. One end of the take-up shaft 3 passes through a support plate 2 and is connected to the output shaft of the first motor 7 disposed outside the support plate 2.

[0023] like Figure 3 As shown, in a further preferred embodiment, an annular rotating plate 32 is provided on the inner side of the baffle 31. The rotating plate 32 is wound around the outside of the winding shaft 3, and the rotating plate 32 and the baffle 31 are connected by two annular bearings 33 of different diameters, allowing the rotating plate 32 to rotate relative to the baffle 31 around the winding shaft 3. The inner side of the baffle 31 contacts the graphite braided wire through the rotating plate 32. Therefore, when the graphite braided wire is wound to the area where both ends approach the baffle 31, it contacts the rotating plate 32, and the rotating plate 32 can rotate with the winding of the graphite braided wire without friction between them, thus avoiding wear on the external metal mesh. Furthermore, the opposite side of the baffle 31 is a flexible rough surface, such as a rough rubber surface used in this embodiment, so that the rotating plate 32 and the graphite braided wire can rotate together better, rather than rotating relative to each other and rubbing against each other.

[0024] The adjusting roller 4 includes two vertically arranged connecting plates 41 and two horizontally installed adjusting shafts 42 between the connecting plates 41. The surfaces of the adjusting shafts 42 are provided with smooth threads, and the threads on the two adjusting shafts 42 rotate in opposite directions. A connecting shaft 43 parallel to the take-up roller is respectively arranged in the middle of the outer side of the connecting plates 41. A second motor 8 fixedly mounted on a bracket is connected to one of the connecting shafts 43. The rotation of the second motor 8 controls the two adjusting shafts 42 to contact the graphite braided wire. When the graphite braided wire passes over the surface of the adjusting shaft 42 and then winds onto the take-up shaft 3, it drives the adjusting shaft 42 to rotate. The rotation of the adjusting shaft 42, in turn, drives the graphite braided wire to move towards one end through its surface threads. This allows the graphite braided wire to move axially while being wound up, thus arranging it evenly and neatly on the take-up shaft 3.

[0025] Preferably, a controller is installed at the power supply of the second motor 8, which controls the second motor 8 to rotate intermittently in both forward and reverse directions. The controller can adopt a dual-relay structure controlled by a PLC circuit board, the principle of which is existing technology and will not be described in detail here.

[0026] In this embodiment, the tensioning roller further includes a sliding shaft 5 and a sliding sleeve 6 sleeved on its outside. The sliding sleeve 6 is a roller structure, and the sliding sleeve 6 is slidably and rotatably connected to the sliding shaft 5, allowing the sliding sleeve 6 to move freely along the axial direction of the sliding shaft 5 while also rotating around the sliding shaft 5. In this embodiment, the graphite braided thread passes through the sliding sleeve 6 before contacting the adjusting shaft 42. Therefore, when it moves left and right under the drive of the adjusting shaft 42, it will not directly contact the sliding shaft 5, avoiding wear on the metal wire and providing further protection.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
